A new milestone has been achieved in the field of solar energy conversion: a highly efficient, stable and inorganic solar cell. A team of scientists from the Institute of Materials Research and Engineering (IMRE) and the University of Singapore has successfully developed a new type of solar cell, made from the inorganic compound CSPBI3 (copper-silver-phosphide-bismuthide-iodine). This new solar cell is able to convert light energy into electrical energy with an efficiency of up to 15.6%, which is among the highest reported for an inorganic solar cell. Moreover, the device is extremely stable over long periods of time, retaining its efficiency even after 1,000 hours of continuous operation. This is an exciting development for the field of solar energy conversion, and could lead to a new generation of efficient and cost-effective solar cells.
